To all whom it may concern:

Be it known that we, LOUIS B. GIRARD and d orin PH Wrirruionn; bothcitizens of the United States, residing at LoskAngeles, in

the county of Los Angeles and State of car ifornia, have invented a newand useful Shade-Adjuster, of which the following. s

specification. i

This invention relates to shade adjusters, and has for its object toprovide a device for enabling the shade roller with its shade to beadjusted vertically to any desired.

the light to come in at the upper part in the desired amount, thusattaining thesame result as though the roller were located at thebottom, with the added advantage that by reason of the roller being atthe top there is no chance for fallingdirt to accumulate on the rollerin the crevice where the "unrolled portion of the shade leaves'theroller.

Another obj ectis to enable'the adjustrnen't to be performed from eithersideoit' the winequally irrespective of from whichsidethe adjustment isperformed. j v I Other advantages will be broughtout in the followingdescription. i

Referring to the drawings: Figure 1 is a front elevation of agwindowfand shade equipped with the invention. .2 is a side elevation ofthe inventionypart of the;

wall being in'section. Fig. 3 is a section on line m 00 Fig. 1. Fig. 4is a sectionlon: line w a*, Fig. 1. -F1g. 511s a section on line w azFig. 1. y On each side of the windowis a pair of vertical bars 1 whicharesupported at their upper ends by a bracket 2which is secured, to thewall 3, and at their lower ends are secured by a bracket 4;, whichisscrewed to. the wall. Each up'perbracket 2 is preferably formed ofsheet metal as shown." Four wing portions 5 amended around the rods 1and is slotted at 6 to receive the screw 7,

A traveling bracket 15 is slidable on each' pair of rods 1 and eachbracket 15has"a ward and thus-prevents the 'shoulderi 14. of

projecting arm 167, and. the arms 16 support -1 ayshade" roller 17. fAttached to each bracket 15, is achain: .18, each chain 18 running overits, associated sprocket l l and extending down and through a projectingarln 19 on1] the lower bracket fl,- the arm 19Lhaving 'a downturnedfinger 20 with which any one of i the links'dfchainlS. may beengaged tohold the chain fand -thus secure :the brackets 15 and shade .roller 17and shade21] in the-de- I sired position, i, m i j V f T ijedower bar22of 1thesha'dehas guide;

1 hold the lower end 'ofgthe'shade stationary if desired, and thenfbymanipulating either of the chainslStheshade roller .17 maybe raised orloweredto shadea greater or less portion of the lower part of-Tthewindow, Toadjustpthe shade to a higher position thanshown in Fig. 1either of thechains 18 may be pulled' down by means of its ring 26 andthis. actionwill release from the fin g 120- Continued downwardmovementof the chain will drawnpwa-rdly onth'e assm,

ciated bracket and raise that end of the shade roller andshade. Atthesame time this movement ofthe chain rotates this sprocket lland thusturnsshaft 12, thereby rotating the opposite sprocketll a correspondingamount and thereby through the chain connected with the latter sprocketwill raise the corresponding end of the shade roller. From this it willbe seen that it is not necessary to exert a pull upon both chains inorder to-adju'st the shade roller as either chain, maybe actuated, orwill be automaticallyoperated as described. Furthermore, it is not evennecessary to disengage the' chain which is not being directlypulledzupon' from. its finger: 20, because as theiother; chainispulleddown it causes the chainqwhich is:- not directly pulled to movedown and this:- automatically relaxes its link from engagement withassociated finger and autom'atically accomplishes the releasingtherefrom. a When the shade is; to be lo'weredgone or the other oii thechains is alsopulledidownsufliciently-to' disengage the fingerEQO,*which movement obviously. causes automatic disengagement of: the otherchain from its. fingers 20, and then the chain is ala lox\"ed:toimove-upwardly and permitthe weightsot' the shade 'roller' and shadewith attached-brackets 1-5 to '1ower to=the desired point when the]chain .18 is: again engaged 1 WithS'fingee-QO and-from further security.

Both. chainsmay be thus engaged with fin- .g'ers 20.; VVhile the shaderoller and shade may thus be adjusted bodily the shade 21 may beoperated in "the usual' manner to of catching dirtin the 1 crevicesbetween the shade more or less of 'then'window by manipulating thelower-bar of the shade, this 1 action. being guided bythe plates 23which insure' a perfect,vertical 'movement of the shade in such"operation-and prevent the shadefrom becoming unevenly rolledupon theshade rolleri. As heretofore indicated, the lowerend of the shade-mayalso be secured bycQrd'Qe, and theni either of the chains 18 may beoperated to move the roller 17 vertically, thereby causing; the shade'toshut oil" the'lower portion of the window and" allow the desired amountof light to come through theupper part of the window only 'or thro'ugh'a' small part at the lower end 50f the window,' as may be desired,thereby: securingrthe-small shading efiect as in that style of shadeswhich "are arranged with their rollers at the bottonr of the window, butwhich are objectionabl'e on account shad'e and theroller portion oftheshade on theroller. The' dogs' 1,4 are capable 'ofholdfing''thesprockets in any desired position, but further se'curityjisafi'orded bybonneCtingcthe' chains-'to' the fingers 20. I

f The I shade roller is preferably secured to ithearms 16' bymeans of?the usual squared spear end 27 which engages in=the arin 16',

and is prevented from turning, and a collar 28 is secured on the spearend 27 by a set screw 29, the collar 28 being adjusted so that? acertain endwise movement of the shade roller is possible with respect tothe arm 16. At the pin end instead of the usual pin, I employ a pin orscrew 30 having a shoulder 31 which takes against a cap 32 on the end ofthe roller 1.7 and has a "smooth shank 33 which can slide in the arm 16a limited distance. This construction which permits a longitudinalmovement of the shade roller with respect to the arms 16 preventsthe-shade from falling out of the brackets in case of emergency, andalso compensates for any disa-rrangemcnt otthe slidmg brackets'lii inwhich one stands higher than the other, although obviously in theregular and normal operation of the device the brackets 15 aremaintained at the same height by the engagement of their chains with thesprockets.
